1 Claim.

An object of our invention is to provide a simple and inexpensive window structure particularly adapted for a basement window, although it can be used for other installations wherever found suitable.

Another object is to provide a window structure including mounting hardware for the sash which permits the sash to move to open position with its top edge moving inwardly relative to the wall in which the window is mounted and with the bottom edge of the sash moving upwardly thus conserving head room necessary for permitting the sash to open. In this connection, the ordinary inswinging sash hinged at its top requires considerable head room for its lower edge to swing when opening the sash and such room is not always available in basements or the like used for the storage of articles.

Another object is to provide a window frame, sash, screen and hardware for the sash which all can be made and assembled at the factory and the parts of which are so related that the entire structure can be readily packaged in a carton,

the hardware particularly being so designed and arranged that it does not project beyond the ,face of the frame and yet does not interfere with the opening action of the window or with weather stripping provided for the periphery of the sash.

A further object is to provide'a window structure including a frame and a sash in the frame, mounting means being provided for the sash in the form of sliding connections and pivoted link connections, such connections being so arranged and located that they do not interfere in any way with weather stripping for the periphery of the sash and do not necessitate notching or otherwise interrupting the weather stripping.

A further object is to provide a window struc- 0 ture wherein the sash may be completely opened to secure full ventilation and yet the necessary head room for opening movement of the sash is comparatively small.

Still a further object is to provide a sash which may be swung inwardly, hardware being provided for mounting the sash which is entirely inward of the inner face of the sash and thereby leaves the periphery of the sash free for the application of uninterrupted weather stripping to the sides and top of the sash.

Still a further object is to provide hardware which so mounts the sash that resilient weather stripping at the sides of the sash serves as a friction means for holding the sash in various positions of open adjustment,

With these and other objects in view, our invention consists in the construction, arrangement and combination of the various parts of our window structure, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in our claim, and illustrated in the accompanying drawing, in which:

Figure 1 is an inside elevation of a window structure embodying our inventiion.

Figure 2 is a horizontal sectional view on the line 2--2 of Figure 1.

Figure 3 is a vertical sectional View on the line 33 of Figure 1 showing the sash in closed position by solid lines and in partly open and full open positions by dash lines and dotted lines respectively.

Figure 4 is an enlarged detail sectional view on the line 4-4 of Figure 3 showing the relation of parts of the window structurewith each other when the sash is fully opened; and

Figure 5 is an enlarged detail sectional view on the line 55 ,of Figure 2 showing further the relation of parts of the window structure.

On the accompanying drawing, we have used the reference numeral H) to indicate the sill of our window'frame. The side jambs thereof are indicated at H and the head jamb at l2. The bottom of the sill l0 and the outer surfaces of the jambs H and 12 are grooved as indicated at I3, l4 and I5 respectively toprovide a bond between the frame and the mortar used for mounting it in a brick or masonry wall.

Within the frame formed by the members H), H and I2, we provide a sash indicated generally at S. The bottom rail thereof is referred to by the reference numeral IS, the top rail by the numeral 11, the stiles by the numerals l8 and the mullions by the numerals l9.

We provide hardware for mounting the sash S for opening movement relative to the frame comprising brackets 2D, 2!" and 22 and links 23. The brackets 20 are angle-shaped and are mount ed in a rabbet 24 along the inner corner of the head jamb l2. The brackets 2| are mounted on the stiles 18 of the sash S at substantially mid-height thereof. The links 23 have their ends pivotally connected to the brackets 20 and 2| by rivets or the like 25 and 26. On the rivets 26, friction washers 2'! may be provided to aid in holding the sash in opened or partly opened position, as will hereinafter appear.

The brackets 22 are mounted on the lower rail I6 of the sash S and include pin like extensions 28. The pins 28 extend into rabbets 29 along the inner corners of the side jambs H and terminate in grooves 30 at the bottoms of the rabbets 29. The grooves 30 extend vertically along the side jambs H in a plane substantially parallel to the inner face of the window frame. The pins 28 and the grooves 30 constitute guide means for the sill edge of the sash S.

The side jambs II and the head jamb l2 are provided with screen stops 3| and 32 respectively. A screen 33 has its frame 34 positioned against the stops 3| and. 32. The upper rail of the screen has a tongue 35 adapted to fit in a groove 36 of the head jamb l2. The tongue and groove connection retains the top edge of the screen in position in the window frame. The

lower edge of the screen is retained in position by a hook or catch 31. The catch 3'l'is pivoted at 38 to the frame 34 of the screen and is adapted to hook on a screw or the like 39 extending upwardly from the sill H). For convenience in opening the window, a lock knob or handle 40 may be provided at its top edge. a

Weather stripping W and W extends along the sides and top of the frame. This stripping as best shown in Figure 4 is of resilient sheet metal (bronze being suitable), having a flange M inserted between the stops 3| and 32 and the grooves of the side and head jambs in which these stops are mounted. The weather stripping has a secondfiange 42 and a third flange 43.

The second and third flanges are doubled one upon the otherand interposed between the jambs and the sash. They provide frictional engagement with the sash to hold it in various adjusted positions. In Figure 4 we illustrate such an engagement when the sash is in its fully opened position. Referring to Figure 3 it will be obvious, due to the type of sash hardware used, that the lower corners of the sash remain in contact with the Weather stripping W throughout the entire opening movement of the sash,thus providing frictional contact to retain the sash in various open positions of adjustment without any auxiliary fasteningmeans. This is a very desirable feature of our invention from the standpoint of operating the window, as it eliminates the necessity of manipulating any adjustable brackets or struts. a

When the sash is moved to closed position the weather stripping W and W effectively seals the sash against infiltration of air between the sash and the frame around thesi-des and top of the sash. The bottom rail l6 of the sash is rabbeted as indicated at 44 and a rib 45 of the sill Ill fits into this rabbet whenthe sash is in closed position.

of the sash is slightly rounded as indicated at 49 (see Figure 3) so that this edge when approaching closed position will engage the weather stripping'W and compress it without, however,

I distorting it.

We have provided a complete window structure which can be readily packaged as hereinbefore set forth and which has hardware permitting full opening of the window and thereby full ventilation through the window frame; The hardware is so mounted and the frame is so rabbeted to receive it, that the hardware in no way interferes with the application of weather stripping to the top and sides of the sash. Such weather stripping can be applied without notching or otherwise interrupting the weather stripping to accommodate brackets or other hardware members. The hardware is so designed and related to the sash and frame that the sash can swing inwardly and yet the hardware does not project beyond the inner face of the window frame. Being mounted inside, the hardware is fully pro tected from the weather by the weather stripping.

Some changes may be made in the construction and arrangement of the parts of our device without departing from the real spirit and purpose of our invention, and it is our intention'to cover by our claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.

We claimas our invention:

In a window structure, a frame including a sill, side jambs and a head jamb, a sash mounted in said frame and means for supporting the sash so that it can be opened relative to said frame comprising guide means for the sill edge of said sash, said guide means extending vertically along said side jambs and link means for said sash, said link means being pivoted to said frame adjacent the head jamb thereof and to said sash adjacent the vertical center between top and bottom thereof, and weather stripping interposed between said jambs and sash and coacting with the side edges of said sash adjacent the sill edge thereof throughoutthe entire movement ofsaid sash from closed to open position, the operating parts of said guide means and said link means being entirely inside said weather stripping.
